    摘要: The invention provides an aqueous pharmaceutical composition for administration as an aerosol to the respiratory tract, nose or oropharyngeal region comprising (i) a macrolide having a poor taste and poor chemical stability in aqueous solution; (ii) at least one salt selected from the group consisting of sodium gluconate, sodium aspartate, sodium acetate, sodium lactate, sodium succinate, sodium maleate, magnesium gluconate, magnesium aspartate, magnesium citrate, magnesium acetate, magnesium lactate, magnesium succinate, and magnesium maleate; or mixtures thereof and (iii) a taste-masking agent different from said salt; wherein (a) the concentration of said macrolide in the composition is in the range of about 0.25 wt.-% to about 15 wt.-%; (b) the molar ratio of said macrolide : said salt is in the range from about 1 : 0.5 to about 1 : 100; (c) the pH of the composition is in the range of about 3 to 9; and (d) the osmolality of the composition is in the range of about 150 mOsmol/kg to about 1500 mOsmo I/kg. The invention further provides a method of generating an aerosol, preferably by means of a nebuliser, which uses such an aqueous pharmaceutical composition. The macrolide may be used alone or in combination with other drugs. The composition is suitable to treat inflammatory disorders and/or infections of the respiratory tract. It has an improved taste and stability.
